Abstract
Description
本創作是有關於一種光源模組,且特別是有關於一種能用於顯示裝置的光源模組以及使用此光源模組的顯示裝置。This creation relates to a light source module, and in particular to a light source module that can be used in a display device and a display device using the light source module.
液晶顯示裝置包括液晶顯示面板與背光模組。由於液晶顯示面板本身不發光,因此需要靠背光模組提供顯示光源至液晶顯示面板。因此,背光模組的主要功能就是提供高輝度以及高均勻度的顯示光源。The liquid crystal display device includes a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not emit light, it is necessary to rely on the backlight module to provide the display light source to the liquid crystal display panel. Therefore, the main function of the backlight module is to provide a high-brightness and high-uniformity display light source.
背光模組在傳統上可分為側入式背光模組與直下式背光模組。一般而言,直下式背光模組適於分區調光(local dimming),光源之間會以隔柵隔開。此外,為了承載光學膜片,發光區的外圍也會配置有邊框。Traditionally, backlight modules can be divided into edge-type backlight modules and direct-type backlight modules. Generally speaking, direct-lit backlight modules are suitable for local dimming, and light sources are separated by barriers. In addition, in order to carry the optical film, a frame is also arranged on the periphery of the light-emitting area.
然而,隔柵與邊框的使用會使得整體的光學亮度降低,導致背光模組的光利用率變差。並且,隔柵會額外增加背光模組的重量,使得液晶顯示裝置整體而言無法朝向輕薄化的方向發展。However, the use of barriers and frames will reduce the overall optical brightness, resulting in poor light utilization efficiency of the backlight module. In addition, the grille will additionally increase the weight of the backlight module, so that the liquid crystal display device as a whole cannot develop in the direction of lightness and thinness.

圖1是本創作一實施例的光源模組的剖面示意圖。圖2是本創作一實施例的光源模組的局部區域俯視示意圖。請參考圖1及圖2,本實施例的光源模組10包括基板100、反射片200、多個發光元件300、黏合層400以及膠框500。反射片200配置於基板100上,並具有側壁210、凸起部220及多個開孔230。多個發光元件300配置於基板100上,這些發光元件300分別對應穿設於這些開孔230。黏合層400例如是配置於基板100及反射片200之間。膠框500配置於基板100上,並圍繞反射片200以及多個發光元件300。FIG. 1 is a schematic cross-sectional view of a light source module according to an embodiment of the invention. FIG. 2 is a schematic top view of a partial area of a light source module according to an embodiment of the invention. Please refer to FIGS. 1 and 2, the
反射片200的凸起部220朝遠離基板100的方向凸起,且於俯視方向上呈現具有多個網眼的網狀結構(如圖2所示),以定義出多個調光區域A。在本實施例中,多個調光區域A例如呈陣列排列,但不以此為限。多個開孔230分別對應於這些調光區域A,意即,每一調光區域A內皆具有一個發光元件300。相鄰的任兩發光元件300之間被反射片200的凸起部220所隔開。此外,凸起部220於基板100上的高度會大於發光元件300於基板100上的高度。藉此,可以降低每一調光區域A內的發光元件300所發出的光線L漏光到另一調光區域A的機率,以避免影響亮度對比及調光效果。圖1及圖2中的多個開孔230及多個調光區域A的數量僅為示意,並不以此為限。The
另一方面,反射片200的側壁210例如是配置於膠框500上。具體而言,側壁210為反射片200接觸於膠框500的延伸部分。膠框500具有頂面510、底面520、外側面530及內側面540。頂面510與底面520相對,外側面530與內側面540相對。在本實施例中,反射片200的側壁210例如配置於內側面540及頂面510上,但不以此為限。在另一實施例中,反射片200的側壁210也可以僅配置於內側面540。On the other hand, the
在本實施例中,反射片200例如為一體成型,但不以此為限。具體而言,反射片200是將平坦的反射片經真空吸塑(Vacuum forming)製程後形成凸起部220。本創作並不特別限制凸起部的形狀,可以依據設計需求調整,並且,反射片200例如也可以是由多片反射片拼接而成。In this embodiment, the
基板100例如是印刷電路板,可為硬板或軟板,用來承載反射片200、發光元件300及膠框500,並透過基板100來驅使發光元件300發光。The
發光元件300可為發光二極體,但也可以是其他種類的發光元件。此外,發光元件300也可以是直接自一片晶圓切割出且未經封裝的發光晶片,例如為發光二極體晶片。舉例而言,所述的發光二極體晶片例如是主波長發出藍光的晶粒級氮化物發光二極體晶片,但不以此為限。圖1的發光元件300的數量是以3個為例,但不以此為限。此外,發光元件300在基板100上呈陣列排列,如圖2所示。應注意的是,圖2旨在呈現凸起部220的形狀以及多個調光區域A與多個發光元件300的排列方式,對於多個調光區域A與多個發光元件300的形狀與數量僅為示意,本創作並不特別限制。The light-emitting
黏合層400的作用在於將反射片200固定於基板100上,因此只要能達到此效果,本創作並不特別限制黏合層400的材質。舉例而言,可以是黏合劑或黏合膠帶,也可以選用具有導熱效果的導熱膠等。在本實施例中,黏合層400例如還配置於基板100及膠框500之間,但不以此為限。習知常見的膠框固定方式為以螺絲鎖固或卡勾固定,然而螺絲鎖固需要花費較長組裝時間,卡勾則容易有變形問題。本實施例的光源模組10直接以黏合層400將膠框500黏合於基板100上,在組裝程序上較為簡單且可以節省時間成本。The role of the
本實施例的光源模組10例如還包括光學膜片組600,配置於膠框500上並由膠框500所承載。光學膜片組600包括至少一光學膜。光學膜片組600的至少一光學膜例如是偏光增亮膜、擴散膜、稜鏡片或複合式稜鏡片等,但不以此為限。本創作並不限制至少一光學膜的數量,其可為一片或多片,在本實施例中是以三片光學膜610、620、630為例,且依序堆疊於膠框500上。此外,依據光學膜功能的不同,光學膜610、620、630也可分別選用不同的種類。應注意的是,圖2中為清楚顯示反射片200的凸起部220的形狀,因此並未繪示光學膜片組600。The
本實施例的光源模組10中,反射片200具有呈現網狀的凸起部220,並定義出多個調光區域A,多個發光元件300分別對應配置於多個調光區域A中。因此,凸起部220可以取代習知直下式光源模組中的隔柵,在達到區域調光效果的同時,還能減輕光源模組10的重量。此外,反射片200的側壁210還配置於膠框500上,由於反射片200本身的反射光線L的效果,使得傳遞至習知直下式光源模組中隔柵或邊框的光線,在本實施例的光源模組10中可以被反射片200反射,進而提升光利用率。In the
圖3是本創作另一實施例的光源模組的剖面示意圖。請參考圖3,本實施例的光源模組10a與上述的光源模組10結構及優點相似,以下僅針對其結構的主要差異處進行說明。本實施例的光源模組10a中,反射片200a的側壁210a例如具有多個貫孔211,並且膠框500a例如為透明導光膠框。原則上,這些貫孔211的孔徑D1小於多個開孔230的孔徑D2,但不以此為限。多個貫孔211的用途在於,使得傳遞至光源模組10a邊緣的光線L能穿過這些貫孔211後入射膠框500a。本實施例的光源模組10a例如還包括反射層700,配置於膠框500a的外側面530及底面520。當光線L入射膠框500a後,可以被反射層700反射後再經由位於膠框500a的頂面510以及內側面540的反射片200a的側壁210a的這些貫孔211出射。本創作並不特別限制貫孔211的數量、尺寸及分布密度等,可以依據設計需求調整。藉由上述設計,本實施例的光源模組10a可以減少不發光的邊框區域,達到邊框薄型化,近似於無邊框的效果。FIG. 3 is a schematic cross-sectional view of a light source module according to another embodiment of the invention. Please refer to FIG. 3, the
在本實施例中,配置於頂面510的反射片200a的側壁210a例如具有彎折部212,適於固定光學膜片組600。具體而言,彎折部212是先朝遠離基板100的方向延伸,再朝向面對多個發光元件300的方向彎折,亦即彎折部212朝遠離基板100的方向延伸後,再沿著實質上平行於基板100且朝向膠框500a所圍繞的區域內的方向彎折延伸,使得彎折部212與位於膠框500a的頂面510的部分反射片200a共同形成類似凹槽狀的結構,使得光學膜片組600的邊緣由位於膠框500a的頂面510的部分反射片200a所承載且位於彎折部212與位於膠框500a的頂面510的部分反射片200a共同形成類似凹槽狀的結構內。本實施例的彎折部212僅為示例,並非限制本創作固定光學膜片組600的方式。彎折部212例如也可以適用於上述的光源模組10。此外,多個貫孔211也配置於彎折部212,例如彎折部212中平行於基板100且朝向膠框500a所圍繞的區域內的方向的部分具有多個貫孔211,因此從膠框500a出射的光線L仍能通過光學膜片組600後,再經由前述彎折部212的多個貫孔211出射,除了可減少不發光的邊框區域,達到無邊框的效果,且可降低光線L直接出射的機會,達到減少邊緣亮線的現象。In this embodiment, the
本實施例的光源模組10a例如還包括遮光層800,配置於膠框500a的外側面530,並延伸至基板100的側面110。遮光層800例如為遮光膠帶或遮光油墨等,但不以此為限。本實施例的遮光層800例如還延伸至彎折部212,意即,遮光層800是配置於光源模組10a的側邊,用於吸收光線以避免漏光。當彎折部212朝遠離基板100的方向延伸的部分不具有貫孔211,以及膠框500a的外側面530配置有反射層700時,也可以不需要再配置遮光層800。The
圖4是本創作另一實施例的光源模組的剖面示意圖。請參考圖4,本實施例的光源模組10b與上述的光源模組10結構及優點相似,以下僅針對其結構的主要差異處進行說明。本實施例的光源模組10b中,反射片200b還具有相對的第一表面201及第二表面202。第一表面201遠離基板100,第二表面202面對基板100。黏合層400例如是連接於第二表面202及基板100。第一表面201例如具有多個微結構240,圖4中是以凸起圓點示意,但不以此為限。這些微結構240可以增加反射片200b散射光線的能力,進而提升光源模組10b整體的出光均勻度。除了微結構240的設計外,於另一實施例中,也可以使第一表面201經粗糙化處理,讓第一表面201的表面粗糙度大於第二表面202,同樣也能達到提升散射光線的效果。上述的設計也可以應用於光源模組10、10a,而彎折部212也可以應用於光源模組10b,本創作並不特別限制光源模組10、10a、10b的結構設計搭配方式。4 is a schematic cross-sectional view of a light source module according to another embodiment of the invention. Please refer to FIG. 4, the
圖5是本創作一實施例的顯示裝置的剖面示意圖。請參考圖5,本實施例的顯示裝置1包括上述的光源模組10以及顯示面板20。顯示面板20配置於光源模組10的出光側。顯示面板20可為液晶顯示面板或其他非自發光顯示面板。光源模組10用以提供面光源L1至顯示面板20,以做為顯示光源。此光源模組10可替換為上述任一實施例的光源模組。由於本實施例之顯示裝置1的光源模組10能提升光利用率,並具有重量較輕的優點,所以使用此光源模組10的顯示裝置1也能提升光利用率,同時也具有重量較輕的優點。FIG. 5 is a schematic cross-sectional view of a display device according to an embodiment of the invention. Please refer to FIG. 5, the
綜上所述,本創作實施例的光源模組中,反射片具有呈現網狀的凸起部,並定義出多個調光區域,多個發光元件分別對應配置於多個調光區域中。因此,凸起部可以取代習知直下式光源模組中的隔柵,在達到區域調光效果的同時,還能減輕光源模組的重量。此外,反射片的側壁還配置於膠框上,由於反射片本身的反射光線的效果,使得傳遞至習知直下式光源模組中隔柵或邊框的光線,在本創作實施例的光源模組中可以被反射片反射,進而提升光利用率。本創作實施例的顯示裝置由於使用上述的光源模組,因此也能提升光利用率,並具有重量較輕的優點。To sum up, in the light source module of this creative embodiment, the reflective sheet has mesh-like protrusions and defines a plurality of dimming regions, and the plurality of light-emitting elements are respectively arranged in the plurality of dimming regions. Therefore, the protrusions can replace the barriers in the conventional direct-type light source module, which can reduce the weight of the light source module while achieving the regional dimming effect. In addition, the side wall of the reflective sheet is also arranged on the plastic frame. Due to the light reflected by the reflective sheet itself, the light transmitted to the grille or frame of the conventional direct-lit light source module is described in the light source module of this creative embodiment. The medium can be reflected by the reflective sheet, thereby improving the light utilization efficiency. Since the display device of this creative embodiment uses the above-mentioned light source module, it can also improve the light utilization rate and has the advantage of lighter weight.
